Oncogenic NRG1 Fusions: A New Hope for Targeted Therapy in Pancreatic Cancer
1Department of Medical Oncology, Dana-Farber Cancer Institute, Boston, Massachusetts. andrew_aguirre@dfci.harvard.edu.
Abstract:
Approximately 8%-10% of pancreatic ductal adenocarcinoma cases are KRAS wild type. In a subset of these tumors, NRG1 gene fusions have been identified as targetable oncogenic drivers, a discovery that highlights the importance of deep molecular characterization for KRAS wild-type pancreatic cancers and provides a novel treatment strategy in this disease.See related article by Jones et al., p. 4674.
Insights
Approximately 8%-10% of pancreatic cancers lack KRAS mutations. In these cases, NRG1 gene fusions are targetable drivers, offering a new treatment strategy. Deep molecular profiling is crucial for identifying these actionable alterations.
Area of Science:
- Oncology
- Molecular Biology
- Genetics
Background:
- Pancreatic ductal adenocarcinoma (PDAC) is a lethal malignancy.
- Most PDAC cases harbor KRAS mutations, limiting targeted therapy options.
- A subset of PDAC is KRAS wild type, necessitating alternative therapeutic strategies.
Purpose of the Study:
- To investigate the role of gene fusions in KRAS wild-type PDAC.
- To identify targetable oncogenic drivers in this specific PDAC subset.
- To highlight the clinical significance of comprehensive molecular characterization.
Main Methods:
- Analysis of tumor samples from patients with KRAS wild-type PDAC.
- Next-generation sequencing (NGS) for detecting gene fusions.
- Identification of NRG1 gene fusions as potential therapeutic targets.
Main Results:
- NRG1 gene fusions were identified in a subset of KRAS wild-type PDAC.
- These NRG1 fusions represent targetable oncogenic drivers.
- This finding underscores the importance of molecular profiling.
Conclusions:
- NRG1 gene fusions are actionable targets in a subset of KRAS wild-type PDAC.
- Deep molecular characterization is essential for identifying novel treatment strategies.
- Targeting NRG1 fusions offers a promising therapeutic avenue for specific PDAC patients.

Cancer-Critical Genes I: Proto-oncogenes
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.
Such genes that act...
Cancer Therapies
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
